Free Windows OS firewall ZoneAlarm

This is a very good question. I have been running Windows based workstation for over 10 years and it’s been a pleasant experience, unless I get the blue screen from time to time. Anyway, I am lately using ZoneAlarm lite firewall software – it’s completely free and is good enough for most home users.
Of course there are a few other firewall software that has better features, but they tend advance to pay use and you have to re-install and always search for a free firewall. This is why I stick to Zonealarm.
